OP was being too ignorant to look into what basically concerns him or her. I believe definitely there must have been a notification message sent to clients  of that casino of their new Terms of Service so as to enable them update their agreement policy with them. This is the normal thing casinos and exchanges do so as to be on the safe side by alerting their clients to update but if the reverse is the case then OP should have known that it is not safe to have left such amount of asset on his account with the casino. It is generally known here that  asset(s) not under your custody is not your own and as such should have be withdrawn with immediate effect. Well, since you have a large followership  or invited referrals under registered with them, I think they would definitely look into it as loyal fan and give you a soft landing.
